PEA FAMILY. Pabaceae. 



There are so many western kinds of Lupinus that ?t is 

 hopeless for the amateur to distinguish them; herbs, 

 sometimes shrubs; leaves palmately-compound, stipules 

 adhering to the base of the leaf-stalk, leaflets, more than 

 three in number, usually closing at mid-day ; flowers showy, 

 in terminal racemes; calyx deeply toothed, two-lipped; 

 standard broad, the edges rolling back, wings lightly ad- 

 hering above, enclosing the incurved, pointed keel, some- 

 times beaked; style incurved, stigma bearded; stamens 

 united by their filaments, alternate anthers shorter; pod 

 two-valved, leathery, flat, oblong; seeds two to twelve. 

 Lupines always have palmately-divided leaves, and are 

 never trailing, twining, or tendril-bearing and thus may be 

 superficially distinguished from Vetches and Peas, and 

 from Thermopsis, by the united stamens. 



A stately perennial, about three feet 



high ' with stout ' branchin g reddish, 

 rivularis slightly downy stems, bearing several tall 



Blue and white spires of flowers. The handsome leaves 

 and purple are bright green, smooth on the upper 



Northwest s ^ e ' ^S^tly downy, but not silvery, on 



the under, with from seven to thirteen 

 leaflets, and the flower-cluster is very erect and compact, 

 eight or ten inches long, beautifully shaded in color, from 

 the pale, silky buds at the tip, to the blue and purple of 

 the open flowers, which are about five-eighths of an inch 

 long, with a lilac standard, tipped with purple. The upper 

 flowers have white wings, veined with blue, and a green 

 calyx, with reddish teeth, and the lower flowers have bright 

 blue wings, veined with purple, and a reddish-purple calyx. 

 This grows in wet places. 



Tree Lu ine ^ cons pi cuous shrub, four to eight feet 



Lupinus arbdreus ni g n witn a tnick trunk, gnarled and 

 Yellow twisted below, with purplish, downy 



Spring branches, silvery twigs and dull bluish- 



green leaves, downy on the under side, 

 with about nine leaflets. The fine flower clusters are 

 sometimes a foot long, composed of beautiful canary- 

 yellow flowers, deliciously sweet-scented. This is easily 

 recognized by its size and fragrance and is common 

 sandy soil near the sea, where it has been found very usefi 

 as its very long roots keep the sand dunes from shifting
